How does hyperosmolar hyperglycaemic state occur?
How does hyperosmolar hyperglycaemic state occur?
HHS occurs when the blood sugar of a person with diabetes becomes too high (hyperglycemia) for a long time. The extra sugar is passed into the urine, which causes the person to urinate frequently. As a result, he or she loses a lot of fluid, which can lead to severe dehydration (extreme thirst).
What is a Nonketotic coma?
Nonketotic hyperosmolar coma is characterized by extremely high plasma glucose without acidosis. Glucose values can exceed 1000 mg/dl, which constitutes sufficient osmolar load to produce significant changes in water compartmentalization. Symptoms generally include polyuria and polydipsia with obtundation or lethargy.
What is Nonketotic hyperosmolar coma?
Nonketotic hyperosmolar coma is a life threatening metabolic derangement that can develop in people with diabetes mellitus, usually due to illness, infection or failure to monitor blood glucose levels.
What is Hyperosmotic coma?
Hyperosmolar coma is also referred to as hyperosmolar hyperglycemic syndrome (HHS) or nonketotic hyperglycemic syndrome. It is characterized by severe hyperglycemia, hyperosmolality, and dehydration in the absence of significant ketoacidosis. Hyperosmolar coma and diabetic ketoacidosis (DKA) are hyperglycemic crises.
Why are there no ketones in HHS?
Serum ketones are not present because the amounts of insulin present in most patients with type 2 diabetes are adequate to suppress ketogenesis.
How can you tell the difference between HKA and HHS?
DKA usually evolves rapidly. In HHS, there is little or no ketoacidosis and the serum glucose concentration frequently exceeds 1000 mg/dL. HHS usually evolves over a period of several days. Overlap between DKA and HHS occurs in more than one-third of patients.
How do you treat Nonketotic hyperosmolar coma?
Treatment typically includes:
- Fluids given through a vein (intravenously) to treat dehydration.
- Insulin given through a vein (intravenously) to lower your blood sugar levels.
- Potassium and sometimes sodium phosphate replacement given through a vein (intravenously) to help your cells function correctly.
What causes hyperosmolar coma?
Diabetic hyperosmolar (hi-pur-oz-MOE-lur) syndrome is a serious condition caused by extremely high blood sugar levels. The condition most commonly occurs in people with type 2 diabetes. It’s often triggered by illness or infection.
What are the signs and symptoms of hyperosmolar syndrome?
Symptoms
- Blood sugar level of 600 milligrams per deciliter (mg/dL) or 33.3 millimoles per liter (mmol/L) or higher.
- Excessive thirst.
- Dry mouth.
- Increased urination.
- Warm, dry skin.
- Fever.
- Drowsiness, confusion.
- Hallucinations.
Which is worse DKA or HHS?
Hyperosmolar hyperglycemic state (HHS) is one of two serious metabolic derangements that occur in patients with diabetes mellitus (DM). It is a life-threatening emergency that, although less common than its counterpart, diabetic ketoacidosis (DKA), has a much higher mortality rate, reaching up to 5-10%.
Why is HHS more common in diabetes 2?
The condition most commonly occurs in people with type 2 diabetes. It’s often triggered by illness or infection. In diabetic hyperosmolar syndrome, your body tries to rid itself of the excess blood sugar by passing it into your urine.
What are the signs and symptoms of HHS?
Is there such thing as a Nonketotic hyperosmolar coma?
Hyperosmolar coma (nonketotic hyperosmolar syndrome) is a state of extreme hyperglycemia, marked dehydration, serum hyperosmolarity, altered mental status, and absence of ketoacidosis. SYNONYMS Nonketotic hyperosmolar syndrome
What do you need to know about nonketotic diabetic coma?
Hyperosmolar coma (nonketotic hyperosmolar syndrome) is a state of extreme hyperglycemia, marked dehydration, serum hyperosmolarity, altered mental status, and absence of ketoacidosis. Evidence of severe dehydration (poor skin turgor, sunken eyeballs, dry mucous membranes)
How often does a patient with hyperglycemic Syndrome go into a coma?
Clinical Manifestations. Approximately 20 to 25 percent of patients who have hyperosmolar hyperglycemic syndrome present in a coma. 2,7 However, many patients have no clouding of consciousness. 2,7 When present, coma is primarily the result of hyperglycemia and hyperosmolarity, not acidosis.
How to diagnose hyperosmolar nonacidotic diabetes mellitus?
The pure hyperosmolar hyperglycemic syndrome, or hyperosmolar nonacidotic diabetes mellitus, is characterized by severe hyperglycemia, hyperosmolarity and dehydration in the absence of significant ketoacidosis. However, the presence of some ketonuria or mild ketonemia does not preclude the diagnosis ( Table 1). 4
